Outlook Data Files are divided into two categories by Microsoft Outlook: PST files and OST files. PST files include data from your personal folders, but OST files contain data from your Exchange Server. Because Outlook cannot import straight from an OST file as it can from a PST file, if you’d like to copy your offline data to some other computer, you can setup the email client to link to your server and generate an additional OST file, or transform your OST contents to the PST format.
